1.1 Package
1.2 Definitions
• 1 package : Outdoor unit.
Split : The heat pump consists of two elements
(an outdoor unit for outside and a hydraulic unit for
inside the dwelling).
Air/water : The surrounding air is the energy source.
This energy is transmitted to the water in the heating
circuit by the heat pump.
Inverter : The fan and compressor speeds are modulated
according to the heating requirements.
This technology enables you to save on energy and
operate on a three-phases power supply, whatever the
heat pump’s output, by avoiding heavy intensities on
start-up.
COP (coefficient of performance) : This is the relationship
between the energy transmitted to the heating circuit
and electrical energy consumed.

Heat pump alféa S excellia 3-phase
1.6 Operating principle
The heat pump transmits the energy contained in the
surrounding air into the dwelling to be heated.
The heat pump consists of four main elements, in which
a refrigerant (R410A) circulates.
--In the evaporator (rep. 13, figure 7, page 10) :
The energy is taken from the surrounding air and is
transmitted to the refrigerant. Because it has a low
boiling point, it changes from the liquid state to the
vapour state, even in cold weather (down to -20 °C
outdoor temperature).
--In the compressor (rep. 10, fig 7 , page 10) :
The vaporised refrigerant brought to high pressure
and takes on more calories.
--In the condenser (rep. 15, figure 8, page 10 ) :
The energy in the refrigerant is transmitted to the
heating circuit. The refrigerant returns to liquid state.
--In the expansion valve (rep. 9, figure 7, page 10) :
The liquefied refrigerant is brought back to low pressure
and returns to its initial temperature and pressure.
The heat pump is equipped with a controller, which
controls the room temperature based on the outdoor
temperature measurement and governed by the
temperature control.
The room thermostat (option) provides a corrective
action for the temperature control.
The hydraulic unit is equipped with an electric back-ups
system, which is triggered to provide additional heat
during the coldest periods.
• Regulation functions
--The heating circuit’s initial temperature is controlled by
the temperature control.
--The power of the outdoor unit is modulated according
to initial heating temperature via the “inverter”
compressor.
--Possibility to set the setpoint of maximun heating initial
temperature.
--Control of the electric back-up heating.
--The daily timer program enables you to define
the periods for comfortable or reduced ambient
temperature.

• Domestic hot water (DHW) operating principle
Two domestic hot water (DHW) temperatures can be
parametered: comfort temperature (line 1610 to 50 °C)
and reduced temperature (line 1612 to 25 °C).
The default heat pump program (line 560, 561 and 562)
is set for comfort temperature from 0.00 to 5.00h and for
reduced temperature for the rest of the day.
This optimises electrical consumption while ensuring
comfortable availability of hot water.
Setting for reduced temperature can be useful to prevent
the DHW from switching on too often and for too long
during the day.
The production of domestic hot water (DHW) is triggered
when the temperature in the tank falls 7°C (setting from
line 5024) below the set temperature.
The heat pump produces the domestic hot water, which
is then supplemented, if required, by electrical backup
heating from the tank.
To ensure a DHW setting over 45°C, the electrical
backup heating or the boiler must be left on.
Depending on how the parameter (1620) is set, comfort
temperature can be reached 24h/day or only at night or
depending on the heat pump programme.
If the contract concluded with the energy provider
includes a subscription to day/night tariff, the electrical
backup is subordinate to the supplier’s power tariff and
the comfort temperature may only be reached at night.
If no particular contract is concluded, the comfort
temperature can be reached at any time, including
during the day
The production of DHW takes priority over heating;
nevertheless the production of DHW is controlled by
cycles that control the times assigned to the heating
and the production of DHW in the event of simultaneous
demand.
A function to switch from "reduced" to "comfort" is
provided on the front of the user interface (see ref. 1,
figure 39, page 29 ).
If the heating installation is equipped with a DHW
circulation pump, the pump’s operation during DHW
cycles can be parametered.
Anti-legionella cycles can be programmed.
• Fan convectors with integrated control system
Do not use a room sensor in the area.
• Protection functions
--Anti-legionella cycle for domestic hot water.

2.6 Refrigeration connections
• To eliminate any filings in the pipes, use dry nitrogen
to avoid introducing any humidity that may adversely
affect the appliances operation. In general, take every
precaution to avoid humidity penetrating into the
appliance.
""This appliance uses refrigerant R410A.
Comply with the legislation for handling refrigerants.
2.6.1 Rules and precautions
• Proceed to insulate the gas and liquid pipes to avoid
any condensation. Use insulating sleeves resistant to
temperatures over 120°C. In addition if the humidity
level in the areas where the refrigeration pipes pass
risks exceeding 70%, protect the pipes with insulating
sleeves. Use a sleeve thicker than 15mm if the humidity
reaches 70~80%, and a sleeve thicker than 20 mm
if the humidity exceeds 80%. If the recommended
thicknesses are not observed under the conditions
described above, condensation will form on the
surface of the insulation material. Lastly, take care to
use insulating sleeves whose thermal conductivity is
0.045 W/mK or less when the temperature is 20°C. The
insulation must be impermeable to resist the passage
of steam during the defrosting cycles (fibreglass wool
is prohibited).
• After every intervention on the refrigeration circuit and
before final connection, take care to replace the plugs
in order to avoid any pollution from the refrigeration
circuit.
• Tools
--Set of manometers with hoses exclusively reserved
for HFCs (Hydrofluorocarbons).
--Vacuum pump specially for HFCs.
--Provision on using tools that have been in contact with
HCFCs (R22 for example) or CFCs.
--Use of a traditional vacuum pump is authorized if, and
only if, it is fitted with a non-return valve on the suction
side.
The manufacturer declines any liability with regard to the
guarantee if the above instructions are not observed.
2.6.2 Refrigeration connections
• Flared connections
The outdoor unit must be connected to the hydraulic
unit with copper pipes and connections (refrigeration
quality), insulated separately.
Comply with the pipe diameters and the permitted pipe
lengths (figure 17).
The minimum length of the refrigeration connections
is 5 m for correct operation.
The appliance will be excluded from guarantee if it is
used with refrigeration connections less than 5 m long.
Manipulate the pipes and take them through walls with
protective plugs in place.
If the distance between the outdoor unit and the
hydraulic unit exceeds the length of the maximum
conduits indicated in the table, an additional charge of
R410A must be loaded.
The quantity of R410A added must be adapted to the
length of the refrigeration circuit in order to the heat
pump’s performance without damaging the compressor
(See para. "Additionnal charge", page 20).
""Lubrication with mineral oil (for R12, R22) is
forbidden.
--Only lubricate with polyolester refrigeration oil (POE).
If POE is not available, fit without lubrication.
• Brazing on the refrigeration circuit (if necessary)
--Silver brazing (40% minimum recommended).
--Brazing only under dry nitrogen internal flux.
Coat the flared surface
with POE refrigeration oil.
Do not use mineral oil.

2.6.4 Shaping the refrigeration pipes
--Cut the pipe to an appropriate length with a pipe-cutter
without deforming it.
--Carefully deburr it, holding the pipe towards the bottom
to avoid introducing filings into the pipe.
--Remove the flared connection nut situated on the valve
to be connected and slip the pipe into the nut.
--Proceed to flare, letting the pipe overflow the flaring tool.
--After flaring, check the condition of the working radius
(L). This must not show any scratch or trace of any
fracturing. Also check the dimension (B).
The refrigeration pipes must be shaped only on a
bending machine or with a bending spring in order to
avoid any risk of crushing or breaking them.
""Warning
• Remove the insulation material locally to bend the
pipes.
• Do not bend the copper to any angle over 90°.
• Never bend pipes more than 3 times in the same
position otherwise traces of fracturing may appear

Additional charge
none
250 g
The charge in the outdoor units corresponds to the
maximum distances between the outdoor unit and the
hydraulic unit defined in figure 17. If the distances are
greater, an additional charge of R410A is required. The
additional charge depends on the distance between
the outdoor unit and the hydraulic unit for each type
of appliance. The additional charge of R410A must
necessarily be made by an approved refrigeration
engineer.
• Example of additional charge :
An outdoor unit 17 m away from the hydraulic unit will
require an additional charge of :
Additional charge = (17 - 15) x 50 = 100 g.
The charge must be introduced after creating the
vacuum and before the hydraulic unit is filled with gas,
as follows :
--Disconnect the vacuum pump (yellow hose) and
connect a bottle of R410A instead in the liquid
extraction position.
--Open the bottle’s valve.
--Bleed the yellow hose by loosening it slightly on the
manifold side.
--Place the bottle on scales with a minimum accuracy of
10 g. Note the weight.
--Carefully open the blue valve slightly and check the
value shown on the scales.
--As soon as the value displayed has dropped by the
value for the calculated additional charge, close the
bottle and disconnect it.
--Then rapidly disconnect the hose connected to the
appliance.
--Proceed to fill the hydraulic unit with gas.
2.7.4 Pump down

2.8 Connecting
the heating circuit hydraulically
2.8.1 General
The connection must comply with good trade practice
according to local building regulations.
The heating circulating pump is built into the hydraulic
unit.
Connect the central heating pipes to the hydraulic unit,
complying with the direction of circulation.
The diameter of the pipes between the hydraulic
unit and the heating collector must be at least 1 inch
(26x34mm).
Calculate the diameter of the pipes according to the flow
rates and the lengths of the hydraulic systems.
Tightening torque : 15 to 35 N.m
Use union connectors to facilitate removing the hydraulic
unit.
Preferentially use connection hoses to avoid transmitting
noise and vibrations to the building.
Connect the drains from the drain valve and the safety
valve to the main sewer system.
Reminder: Seal everything when fitting in accordance
with prevailing trade practice for plumbing work :
--Use suitable seals (fibre seals, o-rings).
--Use Teflon tape or hemp.
--Use sealing paste (synthetic depending on the case).
The use of glycol is not necessary. If you are using a
glycol/water mix, provide for an annual check on the
quantity of glycol.
In certain installations, the presence of different metals
can cause corrosion problems ; the formation of metal
particles and sludge in the hydraulic circuit is then
seen.
In this case, it is advisable to use a corrosion inhibitor in
the proportions indicated by its manufacturer.
It is also necessary to ensure that the treated water
does not become aggressive.
2.8.2 Rinsing out the installation
Before connecting the hydraulic unit to the installation,
rinse out the heating system correctly to eliminate
any particles that may affect the appliance’s correct
operation.
Do not use solvents or aromatic hydrocarbons (petrol,
paraffin, etc.).
In the case of an old installation, provide a sufficiently
large decanting pot with a drain on the return from the
boiler and at the lowest point in the system in order to
collect and remove the impurities.
Add an alkaline product to the water and a dispersant.
Rinse the installation several times before filling it
definitively.
2.8.3 Filling and purging the installation
Check the pipe fixings, the tightness of the connectors
and the stability of the hydraulic unit.
Check the direction in which the water is circulating and
that all the valves open.
Proceed to fill the installation.
Do not operate the circulating pump while filling. Open
all the drain valves in the installation and the bleeder
valve for the hydraulic unit to remove the air contained
in the conduits.
Close the drain and bleeder valves and add water until
the pressure in the hydraulic circuit reaches 1,5 bar.
Check that the hydraulic circuit has been purged
correctly.
Check that there are no leaks and that the circulating
pumps are not seized (if need be, release them).
After the "Start-up" stage (see page 28), once the
machine has started, purge the hydraulic unit again
(2 liters of water).

2.9 Electrical connections
Ensure that the general electrical power supply has
been cut off before starting any repair work.
2.9.1 Characteristic of the electrical supply
The electrical installation must be conducted in
accordance with the prevailing regulations.
The electrical connections must only be made when all
the other fitting operations have been completed (fixing,
assembly, etc.).
""Warning
The contract concluded with the energy provider must
be sufficient not only to cover the heat pump’s power
but also the combined sum of all the appliances likely to
be operating at the same time.
When the power is too low, check with your energy
provider the value subscribed to in your contract.
Never use a socket for the power supply.
The heat pump must be supplied with power by special
protected leads from the electric panel via 2-pole
circuit breakers specially dedicated to the heat pump :
Curve D for the outdoor unit, curve C for the electric
heating and domestic water back-ups (see tables on
page 23).
The electrical installation must necessarily be equipped
with a 30mA differential protection.
This appliance is designed to operate under a nominal
voltage of 400 V, +/- 10%, 50 Hz.
2.9.2 General remarks on electrical connections
It is essential to maintain the live-neutral polarity when
making the electrical connections.
Tighten the screws on the terminal blocks perfectly.
Unsufficient tightening can cause overheating, leading
to breakdown or even a fire.
Use cable clamps to prevent the conductors from being
disconnected accidentally.

2.10 Outdoor sensor
The outdoor sensor is required for the heat pump to
operate correctly.
Consult the fitting instructions on the sensor’s
packaging.
Place the sensor on the coldest part, generally the
northern or north-eastern side.
In any case, it must not be exposed to the morning
sun.
It must be installed so as to be easily accessible but at
least 2,5 m from the floor.
It is essential that it avoid any sources of heat such as
flues, the upper parts of doors and windows, proximity
to extraction vents, the underneath of balconies and
under-eave areas which would isolate the sensor from
variations in the outdoor air temperature.
--Connect the outdoor sensor to the M and B9 terminals
on the heat pump control board.
Installation and operating manual "1363 - EN"
2.11 Room thermostat
and/or room control unit
The room thermostat (room control unit) is optional.
Consult the fitting instructions on the sensor’s
packaging.
The sensor must be installed in the living room area on
a very uncluttered wall, 1,5 m above the floor.
Avoid direct sources of heat (chimney/flue, television,
cooking hobs), draughty areas (ventilation, door, etc.).
Air leaks in the seals in the constructions are often
translated into cold air blowing through the electrical
conduits. Lag the electrical conduits if there is a cold
draught on the back of the IR sensor.
• Installation equipped with two room thermostats.
--Connect each of the sensors to one of the CL+ or CLterminals on the heat pump control board using the
connector supplied.
• Installation equipped with a room thermostat and a
room control unit.
--Connect the sensor to one of the CL+ or CL- terminals
on the heat pump control board.
--Connect the room control unit to the other CL+, CLterminals and to G+.

2.12 Start-up
2.13 Configuring the room thermostat
--Make sure that ALL DIP SW are OFF before starting
up. DIP SW shuold be set OFF for normal operation.
Power supply to the hydraulic unit must be turned off
while toching DIP SW.
--Close the installation’s main circuit breaker.
On first commissioning (or in winter), in order to
allow the compressor to pre-heat, engage the
installation’s main circuit breaker (power supply
to the outdoor unit) some hours before starting
up the tests.
--Engage the start/stop switch.
To ensure that inputs EX4, EX5 and EX6 operate
correctly : Check that the live-neutral polarity of
the electrical supply is correct.
When the power is switched on and every time that the
ON/OFF button is switched off and then switched on
again, the outdoor unit will take approximately 4 minutes
to start up, even if the setting is requesting heating.
The display can show error 370 when the
appliance (re)starts. Do not be concerned, the
communication between the outdoor and hydraulic
unit will re-establish itself in a few moments.
During the regulator initialisation phase, the display
shows all the symbols and then "Data, update" and then
"State heat pump".
--Make all the specific adjustments to the setting
(configuring the installation).
To configure the room thermostat and connect it to the
appropriate heating zone :
--Hold down the presence key for more than 3 seconds.
The room thermostat displays RU and a number
flashes.
--Turn the wheel to choose the zone (1, 2).
OK
--Press the key
.
--Hold down the key
for 3s and select the level of
access used with the aid of the knob
.
OK
--Confirm with the key
.
Parameter the heat pump’s setting (consult the
settings’ list page 32).
On commissioning (or the case of error 10), the electrical
backup heaters are liable to start up even if the outdoor
temperature at the time is above the heaters’ trigger
temperature.
The regulating system uses an average initial outdoor
temperature of 0°C and requires some time to update
this temperature.
To mitigate this situation, the sensor must be connected
correctly. Re-initialise parameter 8703 (implementation
level, consumer diagnostic menu).
- 28 -
""If the installation is fitted with 2 room
thermostats,
- First connect one room thermostat and
configure it in zone 2
- Then connect the other room thermostat and

3.3 Temperature control
The heat pump’s operation is subject to the temperature
control.
The set temperature for the water in the heating circuit
is adjusted according to the outdoor temperature.
The temperature control may be chosen automatically
by the machine (self-adaptation) or set manually by the
installer (Parameters 720, 721 and 726).
If there are thermostatic valves on the installation, these
must be fully open or adjusted for higher than the normal
set temperature.
3.3.1 Manual adjustment
During installation, the temperature control must be
parametered according to the heat emitters and the
dwelling’s insulation.
The temperature control’ curves (figure 41) refer to an
ambient setting of 20°C.
The slope of the temperature control (parameter 720)
determines the impact of the variations in the outdoor
temperature on the initial heating temperature
variations.
The higher the slope, the more a slight reduction in the
outdoor temperature causes a significant increase in
the initial water temperature in the heating circuit.
The off-set in the temperature control (parameter 721)
alters the initial temperature of all the curves, without
altering the slope (figure 42).
The corrective actions in the case of any inconvenience
are detailed in the table (figure 43).
- 30 -
3.3.2 Self-adaptation
When this function is active (parameter 726), the
temperature control are automatically adjusted ; it is
therefore futile to alter the slope or the off-set in the
temperature control (parameters 720 and 721).
When this function is first activated, the end user
may experience some inconvenience for a few days.
This period of no more than a week is required by
the regulator to determine the slope and off-set in the
temperature control.
We advise against changing the temperature settings
during this period.
The following instructions must be observed for the selfadaptation system to operate correctly :
--A room thermostat must be connected.
--The influence of the ambient temperature (parameter
750) must be set between 1 and 100%.
--Depending on the installation, the room thermostat may
have a greater or lesser influence on the temperature
control.
--The room in which the room thermostat is installed
must not contain any thermostatic valves. If this is the
case, the valves must be open fully.
